Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a portable wire feeder and laser processing equipment. Background Technology

[0002] Currently, the wire feeding mechanism is usually integrated on the side or inside of the laser welding equipment and powered by the equipment's own power supply mechanism. This makes the laser welding equipment relatively large and inconvenient to move.

[0003] When the aforementioned wire feeding mechanism is applied to a handheld welding torch, the welding wire delivered from the laser welding equipment needs to pass through a long wire feeding tube before it can be connected to the handheld welding torch. During the welding process, the handheld welding torch needs to drag a long section of the wire feeding tube and the welding wire, which is not only laborious but also inconvenient for welding operations, especially when working at heights. Utility Model Content

[0004] The purpose of this invention is to provide a portable wire feeder and laser processing equipment to solve the problem that current wire feeding mechanisms affect welding operations.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A portable wire feeder includes a main body, on which a suspension part, a wire spool, a wire feeding drive assembly, and a power supply are provided. The power supply is used to power the wire feeding drive assembly, the wire spool is used to wind the welding wire, the wire feeding drive assembly is used to feed the welding wire, and the suspension part is a support structure for suspending the wire on or near the operator.

[0007] In some possible implementations, the main body includes a housing assembly and a mounting plate, wherein the wire spool and the wire feed drive assembly are both mounted on the same side of the mounting plate and are both located within the housing assembly, and the power supply is mounted on the other side of the mounting plate and is located within the housing assembly.

[0008] In some possible implementations, the suspension portion is located on the mounting plate or the housing assembly.

[0009] In some possible implementations, a fixing member is also provided on the mounting plate, the fixing member being used to adjust the resistance relative to the mounting plate when the welding wire spool rotates.

[0010] In some possible implementations, the housing assembly has mounting holes through which the welding wire spool is exposed to the outside.

[0011] In some possible implementations, the wire feeding drive assembly includes a drive wheel, a driven wheel, and a motor. The power source supplies power to the motor, which drives the drive wheel. Both the drive wheel and the driven wheel are rotatably connected to the main body. A wire groove is formed between the peripheral wall of the drive wheel and / or the peripheral wall of the driven wheel. The wire groove is used for the welding wire to pass through so that the drive wheel and the driven wheel clamp the welding wire.

[0012] In some possible implementations, an adjustment component is also included on the main body, the adjustment component being connected to the motor and / or the driven wheel, the adjustment component being used to adjust the distance between the driving wheel and the driven wheel.

[0013] In some possible implementations, a limiting member is also provided on the main body, the limiting member being used to limit the movement of the motor and / or the driven wheel, so that the motor and / or the driven wheel moves in the direction of the line connecting the axis of the driving wheel and the axis of the driven wheel.

[0014] In some possible implementations, the main body is further provided with a wire guide located between the welding wire spool and the wire feeding drive assembly, the wire guide being used to guide the welding wire; and / or, the main body is further provided with a wire nozzle, through which the wire feeding drive assembly delivers the welding wire to the outside of the main body.

[0015] In some possible implementations, a control panel disposed on the main body is also included, the power supply being used to power the control panel, and the control panel being electrically connected to the wire feeding drive assembly.

[0029] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] like Figures 1-4 As shown, this embodiment provides a portable wire feeder, including a main body 1. The main body 1 is provided with a wire spool 2, a wire feeding drive assembly 4 and a power supply 5. The power supply 5 is used to supply power to the wire feeding drive assembly 4. The wire spool 2 is used to wind the welding wire 21, and the wire feeding drive assembly 4 is used to feed the welding wire 21.

[0033] In one embodiment, the main body 1 includes a housing assembly 12 and a mounting plate 11. The wire spool 2, the wire feeding drive assembly 4, and the power supply 5 are all mounted on the mounting plate 11 and located inside the housing assembly 12. The housing assembly 12 serves to protect the internal structure. The wire spool 2 and the wire feeding drive assembly 4 are both mounted on the same side of the mounting plate 11, while the power supply 5 is mounted on the other side of the mounting plate 11, which facilitates the structural layout and avoids excessive compactness.

[0034] In one embodiment, the housing assembly 12 includes a first housing 121 and a second housing 122, with a mounting plate 11 installed between the first housing 121 and the second housing 122, i.e., the first housing 121 and the second housing 122 are respectively installed on two sides of the mounting plate 11. The first housing 121 forms a mounting space with an opening on one side, and the second housing 122 is plate-shaped. The mounting plate 11 is installed inside the first housing 121, and the second housing 122 is installed at the opening of the first housing 121. Optionally, the wire spool 2 and the wire feeding drive assembly 4 are located in the space formed between the mounting plate 11 and the first housing 121, and the power supply 5 is located in the space formed between the mounting plate 11 and the second housing 122.

[0035] In other embodiments, the structures on the mounting plate 11 can be interchanged. For example, the wire spool 2 and the wire feeding drive assembly 4 are located in the space formed between the mounting plate 11 and the second housing 122, and the power supply 5 is located in the space formed between the mounting plate 11 and the first housing 121. The housing assembly 12 can also be provided with multiple housing components according to actual needs. This application embodiment does not limit this.

[0036] The portable wire feeder has an independent power supply 5 to power the wire feeding drive assembly 4, enabling the wire feeding drive assembly 4 to independently feed the welding wire 21 on the welding wire spool 2. Compared with the existing wire feeding mechanism integrated into laser welding equipment, this portable wire feeder can be used independently of laser welding equipment, can be matched with various handheld welding guns of different specifications, and has a compact structure that is easy to carry.

[0037] Alternatively, the power supply 5 can be rechargeable or replaceable, and can be configured in accordance with existing technology.

[0038] The main body 1 is also provided with a suspension part 3, which is used to suspend the main body 1 from the operator's body or a support structure near the operator, so that the main body 1 is suspended from the external structure. Optionally, the suspension part 3 is provided on the mounting plate 11 or the housing assembly 12. Exemplarily, the suspension part 3 is a hook, which is provided on the top of the portable wire feeder, specifically on the first housing 121 or the second housing 122, or the suspension part 3 is provided on the mounting plate 11 and extends through the housing assembly 12. The suspension part 3 and the housing assembly 12 can be an integral structure or a separate structure. In use, the portable wire feeder is suspended on the operator's body or a support structure near the operator through the hook. According to the movement of the handheld welding torch, the suspension position of the portable wire feeder is moved or changed synchronously to keep it close to the handheld welding torch for welding operation. It is more portable when suspended by the suspension part 3, especially for high-altitude operation scenarios, and is convenient to use. In other embodiments, the suspension part 3 can also be a hanging ring, hook, or other structure that can suspend the wire feeder on the operator's body or near the operator.

[0039] The mounting plate 11 is also provided with a fixing member 22, which can adjust the relative position between the welding wire spool 2 and the mounting plate 11 to adjust the resistance of the welding wire spool 2 relative to the mounting plate 11 when it rotates. For example, one end of the fixing member 22 is threaded to the mounting plate 11, and the other end is provided with a knob handle. The fixing member 22 passes through the welding wire spool 2, and the welding wire spool 2 is rotatably connected to the fixing member 22. By turning the knob handle, the depth of the threaded connection of the fixing member 22 to the mounting plate 11 can be adjusted, thereby adjusting the tightness between the welding wire spool 2 and the mounting plate 11, and thus adjusting the frictional resistance of the welding wire spool 2 to the mounting plate 11 when it rotates. It can be understood that the frictional resistance experienced by the welding wire spool 2 from the mounting plate 11 when it rotates can be the frictional resistance formed by the direct contact between the welding wire spool 2 and the mounting plate 11, or the frictional resistance formed when the welding wire spool 2 contacts the threaded seat on the mounting plate 11 for threaded engagement with the fixing member 22. In use, the wire spool 2 is usually adjusted to a state with a certain damping when rotating. This not only prevents the wire spool 2 from rotating on its own when the wire feeding drive assembly 4 stops feeding, thus preventing the wire 21 wrapped on the wire spool 2 from becoming loose, but also keeps the wire 21 taut when the wire feeding drive assembly 4 feeds the wire, ensuring stable wire feeding.

[0040] The housing assembly 12 has a mounting hole 1211 through which the welding wire spool 2 is exposed to the outside. For example, the side wall of the first housing 121 has a mounting hole 1211 that connects the inside and outside of the housing assembly 12. The welding wire spool 2 is located within the opening range of the mounting hole 1211, so that the state of the welding wire spool 2 can be directly observed through the mounting hole 1211, and the tightness of the welding wire spool 2 can be adjusted at any time according to the actual working conditions by means of the fastener 22.

[0041] Mounting hole 1211 is a circular hole with a diameter greater than or equal to the diameter of welding wire spool 2, so that the welding wire spool 2 can be directly installed and removed by passing through mounting hole 1211.

[0042] The wire feeding drive assembly 4 includes a drive wheel 42, a driven wheel 43, and a motor 41. A power supply 5 powers the motor 41, which drives the drive wheel 42, meaning the drive wheel 42 is connected to the output shaft of the motor 41. Both the drive wheel 42 and the driven wheel 43 are rotatably connected to the main body 1. In this embodiment, both the drive wheel 42 and the driven wheel 43 are rotatably connected to the mounting plate 11. A wire groove 44 is provided between the peripheral walls of the drive wheel 42 and the driven wheel 43. The wire groove 44 allows the welding wire 21 from the welding wire spool 2 to pass through, enabling the drive wheel 42 and the driven wheel 43 to clamp the welding wire 21. Exemplarily, one of the drive wheel 42 and the driven wheel 43 has an annular wire groove 44, meaning the wire groove 44 is arranged circumferentially along the drive wheel 42 or the driven wheel 43, and the peripheral wall of the other wheel cooperates with the wire groove 44 to clamp and limit the welding wire 21. Alternatively, both the driving wheel 42 and the driven wheel 43 may have annular wire grooves 44, which work together to clamp and limit the welding wire 21.

[0043] During wire feeding, power is supplied to motor 41 via power source 5. Motor 41 drives drive wheel 42 to rotate. Welding wire 21 on wire spool 2 passes through wire groove 44 during feeding. The distance between drive wheel 42 and driven wheel 43 is such that the distance between the bottoms of the two wire grooves 44 allows welding wire 21 to pass through and is in a clamped state. Thus, when drive wheel 42 rotates, driven wheel 43 and welding wire 21 are synchronously driven to rotate under the action of clamping force, thereby realizing the feeding of welding wire 21. The magnitude of clamping force is such that there is a certain resistance when pulling welding wire 21 when motor 41 is not running, so as to ensure that welding wire 21 will not be easily pulled when motor 41 stops.

[0044] Optionally, the motor 41 and the drive wheel 42 can be directly driven or indirectly driven through a transmission mechanism such as gear transmission or belt transmission.

[0045] The main body 1, i.e., the mounting plate 11, is also provided with an adjustment component 45. The adjustment component 45 is connected to the motor 41 and / or the driven wheel 43, and is used to adjust the distance between the driving wheel 42 and the driven wheel 43. In one embodiment, the driven wheel 43, the driving wheel 42, the motor 41, and the adjustment component 45 are arranged vertically. The adjustment component 45 includes a mounting member 452 and an adjusting member 451. The adjusting member 451 has an external thread, and one end of the adjusting member 451 is rotatably engaged with the motor 41. The mounting member 452 is mounted on the mounting plate 11 and has an internal thread. The adjusting member 451 is threadedly connected to the mounting member 452. By rotating the adjusting member 451, the motor 41 can be raised or lowered to change the distance between the driving wheel 42 and the driven wheel 43, which can accommodate welding wires 21 of different specifications. In other examples, the position of the driven wheel 43 can also be adjusted in the same way as described above, or the positions of the motor 41 and the driven wheel 43 can be adjusted simultaneously, which will not be described in detail here.

[0046] like Figure 3 and Figure 4 As shown, the main body 1 is provided with a limiting member 46, which is used to limit the movement of the motor 41 and / or the driven wheel 43, so that the motor 41 and / or the driven wheel 43 move along the direction of the line connecting the axis of the driving wheel 42 and the axis of the driven wheel 43. Exemplarily, the limiting member 46 includes three limiting plates, wherein one limiting plate is parallel to the mounting plate 11, and the other two limiting plates are perpendicular to the mounting plate 11. The three limiting plates and the mounting plate 11 form a limiting groove with its upper and lower ends connected, so that the motor 41 is located within the limiting groove, thereby limiting the movement of the motor 41 and causing it to rise and fall along the direction of the line connecting the axis of the driving wheel 42 and the axis of the driven wheel 43, preventing deviation.

[0047] The main body 1 is also provided with a wire guide 7, which is located between the wire spool 2 and the wire feeding drive assembly 4. The wire guide 7 is used to guide the welding wire 21. Exemplarily, the wire guide 7 is provided with a wire guide hole 71. The welding wire 21 of the wire spool 2 passes through the wire guide hole 71 and cooperates with the drive wheel 42 and the driven wheel 43. The wire guide hole 71 is used to guide the welding wire 21 so that the welding wire 21 is kept as horizontal as possible when entering the wire groove 44, that is, the welding wire 21 is made as perpendicular as possible to the line connecting the axis of the drive wheel 42 and the axis of the driven wheel 43 when entering the wire groove 44, which helps to ensure the smooth feeding of the welding wire 21. In other embodiments, the wire guide 7 may have a wire guide groove, or the wire guide 7 may be a split structure, with the gap between the two used for guiding the welding wire 21.

[0048] The main body 1 is also provided with a wire feed nozzle 8, through which the wire feeding drive assembly 4 feeds the welding wire 21 to the outside. Exemplarily, the first housing 121 is provided with a wire feed nozzle 8, which communicates with the space formed between the first housing 121 and the mounting plate 11. The welding wire 21 output from the wire groove 44 passes through the wire feed nozzle 8 and is output to the outside of the main body 1. The wire feed nozzle 8 further guides the welding wire 21, ensuring its stable output from the portable wire feeder. In other examples, the wire feed nozzle 8 can also be mounted on the mounting plate 11.

[0049] The main body 1 also includes a control panel 6. Exemplarily, the control panel 6 is mounted on the outer side, and the power supply 5 supplies power to the control panel 6. The control panel 6 is electrically connected to the wire feeding drive assembly 4. The control panel 6 controls the motor 41, for example, by controlling the motor 41's start, stop, and speed, thereby controlling the wire feeding status and speed. Optionally, the control panel 6 controls the on / off state of the power supply 5 to achieve on / off control of the portable wire feeder. In other examples, the control panel 6 can also be mounted on the mounting plate 11 or the first housing 121.

[0050] This embodiment also provides a laser processing device, including the portable wire feeder described above.

[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
